I found this asco by chance on the fruits of Capse
Apothecians that grew, a few days ago, on very humid soil with humus, in riverbank forest with Alnus, Populus and Fraxinus.Apothecia 3-8 mm in diameter. Hairs edge of (243.9) 275.6 - 325.3 (339.7) microns long, with truncated edge almost always, sometimes bifurcated. Shorter exciple hairs, of (138.7) 162.2 - 242.4 (325.7) microns.
Ellipsoidal, verrucous ascospores, of
(18) 18.4 - 20.7 (21.3) × (13.4) 14.1 - 16 (16.6) microns
Q = (1.2) 1.22 - 1.4 (1.5); N = 28
Me = 19.7 x 15.2 microns; Qe = 1.3
Esporal decoration formed by isolated warts of (0.7) 0.9 - 1.4 (1.5) microns in height.
Ascas (238.7) 241.1 - 312.5 (337.2) × (18) 19.5 - 29.3 (30) microns
Paraphysis of (243.9) 275.6 - 325.3 (339.7) microns in length, with terminal element usually widened (6.3) 7.3 - 12.3 (13.4) microns wide.
For the shape, spores decoration and length of the hairs I think of Scutellinia kerguelensis or S. umbrorum. Although I have found in the literature contradictory information on the measures of the hairs and spores decoration in both species.
What is your opinion?
Thank you very much.

Did you try to see if the spore wall loosened in heated cotton blue.
The spore shape and size and the hair features and size you have fit well for S superba. The sketch of the spore in Schumacher shows the spore as broadly ellipsoid like yours but the SEM picture shows a much more ellipsoid shape.
Although the spores are the right shape they look too small and have the wrong ornamentation for S kerguelensis. The hairs are also too short. The spores are a better fit for S umbrorum but again the hairs are a bit short and have the wrong root and number of septa.

Thank you very much for your didactic comments.
I do not have acetic acid nor cotton blue.
I have Lactophenol Blue. Can I do the test with this compound?
